From AdS black holes to supersymmetric flux-branes Original Research Article

We show that AdS black hole solutions admit an analytical continuation to become magnetic flux-branes. Although a static BPS AdS black hole generally has a naked singularity, the BPS flux-brane can be regular everywhere with an appropriate choice of image-charges. This flux-brane interpolates from image at small distance to an asymptotic image-type metric with an image boundary. We also obtain a smooth cosmological solution of de Sitter Einstein–Maxwell gravity which flows from image in the infinite past to a image-type metric, with an image boundary, in the infinite future.
